“…Similar spectra showing the interaction of low-lying Rydberg states with high-lying members of another series have been recorded and analyzed earlier in Sr [55] and Ba [56][57][58]. In such cases, the principal quantum number of the n c p 3/2 nl Rydberg state is lower (n 10) than in the present case and so are those of the perturber series (3p 1/2 nl with n 10-30).…”

“…Particularly, as far as the Sr atom is concerned, the autoionizing states observed up to now belong to the odd configurations 4dnI (J = i) [2][3][4][5], 5 pnl (J = 1) [5][6][7], 4dnl (J=3) [8] and 5pnd (J=3) [9], while only the 4d5d (J=l-5) and a few 4d6d members of the even states are reported up to now [10].…”

Abstract.We have measured the energies of a few hundreds of even parity, J = 0-3 autoionizing 4 d nl Ry states of strontium using an optogalvanic spectroscopy technique. These states are reached by a two-step pulsed dye laser excitation from the 4d 5s metastables through the 4d5p 3Po, 1, 2 intermediate states. Electronic collisions populate the 4d 5s states in a d.c. glow discharge through a Sr plus He vapour in a heated quartz cell. The electronic configuration for the majority of the observed Sr states is deduced from their quantum defect values and other characteristics of the corresponding transitions.

“…Extrapolating Refs. [61] and [62], we estimate autoionization spectral widths (γ AI ) of 10 and 30 GHz for the 5s48s 1 D 2 states, respectively. For our 422 nm laser intensity, core excitation for S and D Rydberg states is thus very weak and unlikely during our 500 ns LIF pulse.…”

Imaging the evolution of an ultracold strontium Rydberg gas

Clouds of ultracold strontium 5s48s 1 S 0 or 5s47d 1 D 2 Rydberg atoms are created by two-photon excitation of laser-cooled 5s 2 1 S 0 atoms. The spontaneous evolution of the cloud of low orbital angular momentum (low-) Rydberg states towards an ultracold neutral plasma is observed by imaging resonant light scattered from core ions, a technique that provides both spatial and temporal resolution. Evolution is observed to be faster for the S states, which display isotropic attractive interactions, than for the D states, which exhibit anisotropic, principally repulsive interactions. Immersion of the atoms in a dilute ultracold neutral plasma speeds up the evolution and allows the number of Rydberg atoms initially created to be determined.
